Abstract
An assembly measures a bending torque on a machine element extending on an axis using the inverse magnetostrictive effect. The machine element has a cavity and at least one magnetization region, extending circumferentially around the axis. A magnetic sensor is arranged in the cavity to measure a directional component of a magnetic field which is brought about by the magnetization and by the bending torque. A second directional component of the magnetic field may be measured by the magnetic sensor or by another magnetic sensor.
